Karen Toshima, a young Long Beach woman with a promising career as a graphic artist, was shot in the head as she strolled in Westwood, the innocent victim of a bullet fired in a gang fight.

Today, Takakjian begins the defense in court of the man accused of firing the fatal shot.

And the repercussions of that shot continue to reverberate throughout the city.

Toshima's shooting 19 months ago carried an ominous message--that the gang violence that had plagued poor, minority neighborhoods in South and East Los Angeles for years had escaped its imaginary boundaries.

Seen as Watershed

Suddenly Los Angeles--and the nation--awakened to the fact that the gang problem was no longer just a neighborhood concern.

The killing "was one of those watershed-type moments," said Joseph Duff, president of the Los Angeles NAACP. People "became aware of the fact that these problems are non-containable."

Police changed their tactics and redoubled their efforts to combat gang violence citywide, and stories of gang killings began to dominate the nightly news.

Karen Toshima came to represent "everywoman," and her death made all of Los Angeles feel more vulnerable.

Toshima was killed on a Saturday night as she walked along a Westwood street crowded with visitors. Rival gang factions had spotted each other on Broxton Avenue and hurled insults before one of them fired across the street, hitting Toshima in the head.

After a night on life-support systems, she died Jan. 31, 1988, at the UCLA Medical Center.

Immediately after the shooting, police rounded up scores of bystanders, including several members of the two gang factions involved in the deadly feud. They were questioned and released.

One week later, Durrell Dewitt Collins, 23, an alleged member of a Crips faction, was arrested at his Southwest Los Angeles home and charged with Toshima's murder and the attempted murder of a rival gang member who was the alleged target of the bullet.

At his preliminary hearing, three eyewitnesses testified they saw Collins fire the shot that killed Toshima. But Takakjian, ordered by the court last March to represent Collins after a succession of attorneys withdrew for varying reasons, says his defense will hinge on "an identity question"--whether it was actually Collins or another gang member who fired the fatal shot.

What is not in question is that gang violence cost the young woman her life.

In the wake of Toshima's death, Los Angeles police tripled patrols in the upscale Westwood Village area and devoted 30 officers to the murder investigation.

That show of police strength spawned criticism by black and Latino community leaders, who complained that gang shootings in South and East Los Angeles had generated no such dramatic police response.

That, in turn, led to a surge in police activity, especially in South Los Angeles, and a change in police tactics that included the introduction of Operation Hammer--massive police sweeps aimed at interrogating and arresting suspected gang members. The twin aim was to make life miserable for the gang members and make police visible to area residents.

Operation Hammer was a "spontaneous" reaction to Toshima's death, an "outgrowth of a lot of frustration and an outrageous level of violence . . . which all seemed to crystallize in the city when Karen was killed," said Deputy Chief Bill Rathburn, commanding officer of the Los Angeles Police Department's South Bureau.

"It's ironic," said Takakjian, a former deputy district attorney who spent three years as a member of the D.A.'s hard-core gang unit before he went into private practice in 1987.

"Several years before, in '85 or '86, . . . I wrote a memorandum saying there was beginning to be an influx of gang members in the Westwood area, and it was something we should concentrate on because it was just a question of time before something exploded and someone was hurt.

"That's just what happened. You had rival gangs, somebody took a shot, hit an innocent bystander. . . . Tragically, it took something like this to really get people off the dime."

To pay for special patrols like Operation Hammer, Los Angeles city and county officials allocated nearly $6 million in emergency law enforcement assistance funds in the months after Toshima's death.

Fewer than two weeks after the slaying, the Los Angeles City Council approved hiring 150 more police officers. Several months later, the council voted to fund an additional 514 officers, which will bring the department to record strength--more than 8,000 police officers--by next June.

Deployment of Officers

Toshima's death also rekindled the debate over deployment of officers, and the month after the slaying, changes were made in the deployment formula to put more officers on patrol throughout the city.

But the legacy of the Toshima murder may rest less in the outcome of Collins' trial and more in the vigor and direction of the attack on gang violence in this city.
